Bl4ck32....why did you go with a custom 1 piece tailshaft?

Cubes et al....is there actually that much meat on the '32 engine mounts that you can slot them 13/15 mm? On the R33 the mounts are minimalist alloy items and that much would almost cut through. Since my entire front end is now on a pallet on the floor I may take some pictures and measurements of my setup...

Just thought I would bump this 20 year old thread because the Skid Factory have just posted up a video summarising a lot of the content, format might be more familiar for newer members

fyi guys, Well yesturday i picked up a RB30 for my conversion into my R33. I will be using my RB25DET head on the RB30 block. So i started stripping the motor down, pulled the crank, pistons, girdle

In your PDF its says that u changed the 25 idler pulley to a tensioner pulley.

Were these 30 or 25 items?.

My 25 pulleys are rooted, I can get 2 x 30 tensioners (I asked for VL RB30E ones) for cheaper than 25 ones, also how much did u get ur Gates 94407 timing belt for?

cheers. :rofl:

I've got a question, when you guys have relocated the tensioners, have you tapped the spike/bolt for the spring to push/spring on, to get the self tensioning effect, or have you just adjusted them by hand and tightened them, if you know what i mean....

I'd like to know too.

The RB30E tensioner pulley has a second stud to stop the spring from spinning around, I havent seen anyone use the second stud in a RB30/25/26

This is from memory.. (again) lol

The drivers side is basically a piece of sheet metal shaped in to an engine mount. That was redrilled with no issues, old holes then filled in and hit it with the grinder.

The passenger side engine mount had the flat plate bit that bolts on to the engine ground off then rewelded (much better I might add) lower.

The tensioners are all the same, RB30/20/25/26.

I bought a new RB20DET item which used 2 internal bearings next to each other.

I then ordered a RB30 item as they had them in stock and found they only use one bearing. lol Typical holden. :P

I didn't bother with the spring as the tensioners are locking tensioners and require roughly 20kg's of tension on the belt.

The spring doesn't tension the belt correctly, it pulls up the slack to make life easier when fitting.

The belt.. $37.50.

r33 gearbox (with custom gearbox x member to bolt it into a r32), tailshaft, and modified speedo sender came out of another r32. Also had the r33 yoke etc. So it was a bolt in upgrade from that point.

It weighs heaps less too. I dont know how that would affect performance though :) ....or....lack of :rofl:

Ben,

 

Stupid me.. I didn't write it down anywhere.

 

It may be on my oldies computer as that is where I dropped the motor in.

Failing that I will give Shaun a buzz as he knows :(

Oh great! lol..

Well I am probably going to do it tomorrow.. so if your around.. please try and get the info! :D

I just like the idea of not having to worry about a worn belt letting go, or a tensioner bearing bolt snapping to blow my motor. I reckon around 80,000 is a good time...hell why not 50,000 kms when the two tensioners + belt comes to $220 for a major service.. :)

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.

      Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)

      Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.

      Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
